Display Device Writing Content Transfer During Image Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices fail to reflect writing content in one area on a display surface when switching images from another area, leading to incomplete display of written content.
Innovation Solution
A method and display device that superimpose writing images onto one image in a second area, allowing for seamless transition and display of written content by changing images in both areas based on specific conditions, ensuring the written content is displayed correctly when image switching occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device displays a first image in a first area and a second image in a second area, then the display device can show multiple images simultaneously, but when switching to a new image in the second area, the writing content from the second area is not reflected in the first area
Solution Approach 1:
The system performs preliminary action by capturing the writing content from the second area before the image switch occurs. The writing information is pre-processed and stored in readiness, so that when the image switch happens, the writing content is already prepared to be transferred to the first area, preventing any loss of writing information during the transition.
Solution Approach 2:
The system introduces an intermediary mechanism that acts as a bridge between the second area (where writing occurs) and the first area (where content is displayed). This intermediary captures the writing content and facilitates its transfer to the first area during image switching, ensuring that writing information is preserved and displayed correctly after the switch.
2Ease of operation
If the display device displays the first image in the first area after receiving second image data, then the display device maintains simple image switching operation, but the writing content performed in the second area is not displayed in the first area
Solution Approach 1:
The system implements self-service by automatically detecting and capturing writing content from the second area during image switching operations. The display device autonomously performs the task of transferring writing information to the first area without requiring additional user actions, thus maintaining ease of operation while preventing writing content loss.
Solution Approach 2:
The system uses feedback mechanisms to monitor the image switching process and detect when writing content needs to be transferred. The feedback loop ensures that the writing information is captured and displayed in the first area at the appropriate moment, maintaining both operational simplicity and information integrity.
3Reliability
If the display device superimposes writing image on the second image in the second area, then the writing content is preserved in the second area, but the first area continues to display the original first image without the writing content
Solution Approach 1:
The system applies segmentation by separating the display surface into distinct functional areas: the first area for displaying transferred writing content and the second area for active writing and new image display. This segmentation allows independent management of each area, enabling reliable writing content preservation in the second area while simplifying the transfer process to the first area, thus managing device complexity through clear area differentiation.

AI summary
A method of operation performed by a display device displaying an image on a display surface includes the steps of displaying a first image in the display surface's first area, and displaying second image in a second area different from the display surface's first area, displaying a third image formed by superimposing a writing image to the second image on the second image in second area instead of the second image, determining whether or not a condition for changing an image to be displayed in the first and second area is fulfilled, and changing the image to be displayed in the first area from first image to third image and changing image to be displayed in second area from third image to a fourth image when it is determined that the condition is wherein the first image is displayed in first area and third image is displayed in second area.
